365-Day
Astronomic
Time Switch
ET90000 Series
Intermatic’s Most Versatile Time Switch
Flexible program options and low-voltage inputs help customize
the schedule to meet the requirements of almost any application
The ET90000 Series 365-Day Astronomic
Time Switches feature independent, 365-day
programming that meet the demanding needs of
any facility schedule. These state-of-the art time
switches provide reliable performance with to-theminute accuracy that reduces energy costs. Superior
memory accommodates up to 4,000 set points or
events, plus holiday and exception programming.
Easy-to-use control buttons permit independent
manual control of each circuit regardless of the
operating mode.
The intuitive time switches automatically detect
and adjust voltage between 120 and 277 VAC,and
operate at 50 or 60 Hz, which eliminates the need
for manual voltage adjustments during installation.
Exceptional versatility enables circuits to be added
after installation. Automatic Daylight Saving Time
feature can adjust the clock and the programmed
schedule throughout the year. All models are
equipped with a powerful 100-hour supercapacitor
that maintains dates and times during a power
outage and then automatically recharges in less
than 30 minutes after power is restored. Software
updating is made easy with the USB connection and
Ethernet capabilities that enable in-field firmware
upgrades to be installed remotely from one central
location. These powerful time switches can be
used with external devices such as wall switches
and occupancy/vacancy sensors to manually turn
ON and time OFF.
All models are securely housed in a lockable
enclosure to protect against unauthorized entry,
thus keeping the invaluable time switches under
your control.
